Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an acquisition device and an acquisition method of an eye diagram compensation curve of an optical module. Background technique [0002] When the optical module is used, as the temperature changes, the MCU (micro processing unit) needs to compensate the transmitted optical power and extinction ratio of the optical module to ensure the stability of the transmitted optical power and extinction ratio of the optical module. When adjusting the transmitted optical power and extinction ratio of the optical module, it is set by adjusting the adjustable potentiometer of the LD (Laser Diode, laser diode) chip inside the optical module or the external resistor; when the temperature changes, the slope efficiency of the LD chip will change. In order to keep the transmitted optical power of the optical module stable, it is necessary to compensate the bias current of the optical m...
